FUEL-BURNER.

SPECIFICATION forming part of Letters Patent No 762,048, dated June '7, 1904.

Application filed July 16, 1903.- Serial No. 165.823. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM E. GIBBS, a citizen of the United States, residing at Fanwood, in the county of Union and State of New 5 J ersey, have invented certain new and useful Improvements in Fuel-Burners, of which the following is a specification.

My invention relates to improvements in devicel s for burning hydrocarbons or pulverized 1o fue The object of my invention is to provide an,

improved burner for either hydrocarbons or pulverized fuels-such, for instance, as pulverized coalin which there will be an eco- I5 nomical use of fuel to obtain an extremely high temperature.

Further objects of my invention are to provide many improved details of structure fully hereinafter described, and shown in the ac- 20 companying drawings, in which like reference characters refer to like parts, and in which Figure 1 is a. plan view of my improved burner as especially adapted for use of hydrocarbons as fuel and in which the feeding de- 2 5 vice has been removed. Fig. 2 is a sectional elevation of the same, showing also a portion of the feeding device. Fig. 3 is a sectional plan of my improved burner as especially adapted for use of pulverized fuels, and Fig.

3 4 is a sectional elevation of the same.

Referring in detail to the drawings, in the construction shown in Figs. 1 and 2, 1 represents a circular head having depending therefrom bolts 2, sustaining a casing 3 of a tur- 3 5 bine-engine of any suitable construction, in which 4 indicates the inlet and 5 the exhaust ports. 6 is a sleeve surrounding bolts 2. Gentrally mounted in casing 3 in suitable bearings therein is a vertical shaft 7, upon which said 4 engine is mounted. Rigidly supported at the upper end of shaft 7 is a disk 8, having a centrally-depending tubular portion 9, with fanshaped radial arms 10 extending slightly above the surface of the disk 8 and connected to said shaft by screw 11,said shaft extending through a central perforation 12 in the head 1. Disk 8 is provided on its under surface with radial from the circumference and over the annular fications of structure wherein I dispense with the central tubular portion 9 and arms 10, 6o employing a plain disk 17, provided with the annular flange 14 and blades 13, and a central air-tube 18, preferably of refractory material, extending downwardly to a point immediately above the disk 17, to deliver an opposing curi rent of air to the said disk, said tube 13 having centrally located therein a fuel-tube 19, extending down to a point above disk 17 and surrounding an extension 20 of shaft 7, said extension 20 carrying spiral conveyer-bladcs 7o 21, playing in tube 19. At head of tube 19 is a funnel 22. 23 represents portions of a furnace, and 2 1 an annular flange on head 1.

The operation of my burner is as follows: In the construction shown in Figs. 1 and 2, hydrocarbon being delivered by pipe 16 to disk 8, which is rotated at a suitable rate of speed by the rotary engine in casing 3, the same is thrown tangentially outward in a fine spray, such spray being caused partly by the 8 liquid striking the surface of the disk 8, partly by said liquid being forced outwardly against the annular flange 14, and partly by the current of air ascending through tubular portion 9 of disk 8 and induced by'fan-shaped radial 5 armslO and blades 13, which also force such central draft tangentially outward, such draft cooperating with an under draft induced by blades 13 through perforation 12 and saucershaped depression 1 5. The fineness of such 9 spray may be regulated by introducing a greater or less amount of steam into casing 3 to increase or diminish the speed of the rotary engine, and therefore of the rotary disk 8. It is absolutely essential that there be a central draft passing outwardly toward the circumference of said disk, as otherwise the spray, and consequently the flame, would be forced to recurve onto the disk 8 and the efficiency of the burner thereby greatly impaired.

Figs. 3 and I show a feed mechanism which is especially adapted for feeding pulverized fuel to the rotary disk, (in these figures designated at 17 Such a feed mechanism forms a positive method of feeding fuel and consists in an extension 20 of shaft 7, carrying spiral conveyor-blades 21, adapted to play in a fuel-tube 19 to feed fuel from a funnel 22 at the upper end of said tube 19. Surrounding tube 19 is an air-tube 18, adapted to deliver an opposing current of air to the disk 17 to prevent recurving of the spray of fuel and its resulting flame in a manner already described, such current of air being induced by blades 13 and cooperating with the under current of air passing through the depression 15. With this form of fuel-feeding means, the pitch of the screw havingbeen determined for good combustion at one rate of burning, fuel will be fed to the disk in very close relation to the current of air descendingthrough tube 18 in proportion to the speed of the engine. Thus the rate of combustion may be varied and yet the same quality of flame maintained, although the size of the flame is increased or decreased, as desired. Moreover, when the burner is applied to a furnace, as shown in the drawings, in which 23 represents portions of a furnace, and 24V represents an annular flange on head 1, by which said head is securely seated in the furnace, tube 18 will serve to prevent heavy objectssuch, for instance, as pieces of iron ore from falling onto the disk 17 and its surrounding parts.

The bolts 2 passing through casing 3, it is necessary to provide sleeves 6 to prevent escape of steam from the casing 3.

It is obvious that any means other than a steam-turbine may be employed for rotating disks 8 and 17such, for instance, as bevelgearing, belting, and other means and that my burner can be put to many different uses.

I do not wish to be understood as limiting myself to the exact details of structure herein shown and described, inasmuch as the same may be varied at will without departing from the spirit of my invention.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a burner, the combination with a rotating disk, and means carried by said disk for inducing a current of air in one direction, of means opposing said disk for delivering a current of air in a direction opposite to the current of air induced by said disk, and means for delivering fuel to said disk.

2. In a burner, the combination with a 1'0- tating disk, and means carried by said disk for inducing a current of air in one direction,

of means opposing said disk for delivering a current of air in a direction opposite to the direction of the current of air induced by said disk, and means for delivering fuel to said disk through the opposing current of air.

3. In a burner, the combination with a rotating disk, and means carried by said disk for inducing a current of air in one direction, means for inducing a current of air in an opposite direction to the direction of the current of air induced by the disk, and means for delivering fuel to said disk.

7 In a burner, the combination with a rotating disk, of fan-blades on said disk, of a depending air-tube above said disk, and means for delivering fuel through said tube to said disk.

8. In a burner, the combination with a circular head having a saucer-shaped depression therein, of a central perforation in said depression, of a disk rotating in said depression and having a central tubular portion depending in said perforation, of blades car ried by said disk, of means for rotating said disk, and means for delivering fuelt-o said disk.

9. In a burner, the combination with a circular head having a saucer-shaped depression therein, of a central perforation in said depression, of a disk rotating in said depression and having a central tubular portion depending in the perforation, of a shaft, means for rotating said shaft, radial arms connecting said shaft with said disk, of radial blades mounted on said disk, and means for delivering fuel to said disk.

10. In a burner, the combination with a retating disk, means delivering a current of air to the upper surface of said disk, means for delivering an opposing current of air from beneath said disk, and means delivering fuel to said disk.
